To the Editor: Dr Saper and colleagues1 found that approximately 20% of Ayurvedic products sold over the Internet contained heavy metals, and the metal content was higher among a subgroup of products classified as rasa shastra. Although the efforts to establish that metal content in these products may potentially present a public health hazard are important, we caution against their policy conclusion: “We suggest strictly enforced, government-mandated daily dose limits for toxic metals in all dietary supplements and requirements that all manufacturers demonstrate compliance through independent third-party testing.”
